Equipment Data

Task has resource requirements and this is determined by the nature of the task and the volume involved. The nature of task is mainly dictated by the attributes of part, in other words the relationship the object has with the action involved. This relationship is data centred and it is possible to determine this through inference mechanisms. The process designer infers through experience, whereas software engineering on the other hand allows this to be done automatically. When task is associated internally with the object, the attributes of the task are interrogated in relation to the attributes of object. This interrogation allows for the selection of correct equipment based on the dimensional attributes of object This mechanism can be extended to other resource requirements.

After all the tasks have been analysed in this manner it becomes possible to integrate the information on time and cost and output the summary as shown in Fig. 4.5. This information incorporates all aspects of the part manufacture. When this part is used in the assembly planning it appears as a live relationship. Any changes in it are directly reflected in the assembly planning information and this enables the connectivity of all process information in an integrated fashion. 

Assembly is a part constituted by other parts through Bill of Materials (BOM). Sometimes the parts constituting the final assembly are also assemblies themselves and they are called sub-assemblies. In large products the parts lead to sub-assemblies, which then become parts in higher-level sub-assemblies. All the sub-assemblies eventually merge to create the final assembly or product. This is evident in all the sophisticated products and it is the only way to manufacture

Again we are able to simulate the assembly process narrative and this time the objects are all the individual parts constituting the BOM as illustrated in Fig. 4.7.
